Husqvarna Construction Products has a policy of continuous product
development. Husqvarna reserves the right to modify the design and
appearance of products without prior notice and without further
obligation introduce design modifications.
• The DM 230 is an electric handheld drill, intended for drilling
concrete, brick and various stone materials.
• The drilling machine has a modular design and is easy to
assemble.
• The machine is equipped with spirit levels to facilitate drilling
and a swivel handle with an integrated adapter for support pins to
make the work more comfortable.
• DM 230 has three speed ranges for drill bit sizes up to 150
mm.
• The machine has a water cooled gearbox with a pipe that runs
through the spindle.
• DM 230 can also be connected to a vacuum cleaner with the help of
an adapter, used for dry drilling, which is attached to the
spindle.
• The drilling machine is equipped with SoftstartTM, SmartstartTM,
ElgardTM and speed control.
SoftstartTM
SoftstartTM is an electronic power limitation, making it easier to
start the drill. Maximum speed is reached in about three seconds
after the power switch is pressed in.
SmartstartTM
If the SmartstartTM button is pressed in directly after the power
switch is pressed in, the speed is reduced by 50%. In SmartstartTM
mode the machine has less power until the button is pressed in
again. These functions are of great use for creating a pilot hole
for drilling.
ElgardTM
ElgardTM is an electronic overload protection.
If the motor is overloaded, the overload protection pulses the
motor. Reduce the load and the motor returns to its normal speed.
The overload protection disconnects the power, if the machine is
subjected to heavy loads or if the drill bit jams. The machine is
reset by first releasing the power switch and then pressing it in
again. If the drill bit jams, the mechanical slip clutch protects
the gearbox before the overload protection disconnects the
power.
Speed control
Speed control always gives maximum output power from the machine.
The speed control function provides the machine with a limited
idling speed.
Ergonomics
The soft rear section on the DM 230 has a large contact area so
that the machine sits better against the body. The rounded handle
makes the machine comfortable to hold while drilling. The
protective loop forms a practical carry handle when
transporting.

WORKING TECHNIQUES
Using the machine • The machine has a very high torque. This
demands good
concentration during work, as serious personal injuries can occur
if the drill bit suddenly jams.
• Keep your hands at a safe distance from the drill spindle and
drill bit when the machine is running.
• Keep an eye open for oil or water leakage. If water or oil
trickles out from the leakage hole on the top of the pinion neck,
the seals must be replaced
Handheld drilling
• Always use a drill bit with a max. diameter of 75 mm with
handheld drilling. The larger the drill bit the greater the
reaction if the drill jams.
• Always make sure you are standing firmly when carrying out
handheld drilling.
Stand drilling
• Always use a drilling stand if drilling is to be performed from a
ladder or scaffold.
Handheld drilling in these situations is full of risks, as the risk
of falling is very high if the drill bit jams.
• Make sure that the stand is secured correctly.
• Make sure that the drilling machine is secured correctly in the
stand.
Drilling outdoors
• Always use extension cables that are approved for outdoor
use.
Drilling in ceilings and the like
• Use a water collector to avoid water penetrating into the
machine. The machine must be covered with plastic or the like in
order to prevent water penetrating into the machine, but do not
cover the air intakes and air outlets.
Changing the drill bit
2 Get:
- The supplied open-ended spanners, size 24 mm and 32 mm.
- Water-resistant grease.
3 Remove the old drill bit using the open-ended spanners.
4 Apply water-resistant grease to the thread of the new drill
bit.
5 Attach the drill bit using the open-ended spanners.
Before the machine is started, carefully check that the new bit is
firmly attached.
! WARNING! Do not perform handheld drilling in first gear as the
machine has a powerful torque that can result in personal injuries
should the drill bit jam.
IMPORTANT! The air intake must not be covered.
